There is a proposal for async event listeners: https://github.com/whatwg/dom/issues/1308

Several use cases identified as related (https://github.com/whatwg/dom/issues/1308#issuecomment-2312993127):

  • "passive" event dispatch. Observe, but don't block, event dispatch. Don't need preventDefault.
  • lazy loading "controllers", aka progressive hydration.
  • Tracking long running "async effects" which follow the sync event dispatch.
  • "document still loading" use cases
  • "document started unloading" use cases
